Structural Example of Data Processor

The data processor 100 described in this embodiment includes an input/output device 120 that receives first image data V1 and second image data V2 and supplies first positional data L1 and second positional data L2, and an arithmetic device 110 that supplies the first image data V1 and the second image data V2 and receives the first positional data L1 and the second positional data L2 (see FIG. 1).

The input/output device 120 includes a first region 120(1), a second region 120(2), and a bend portion 120(3) between the first region 120(1) and the second region 120(2) (see FIGS. 2A and 2B).

The first region 120(1) includes a first display portion 130(1) and a first positional data input portion 140(1) that overlaps with the first display portion 130(1) (see FIGS. 2B and 2C1).

The second region 120(2) includes a second display portion 130(2) and a second positional data input portion 140(2) that overlaps with the second display portion 130(2).

The first display portion 130(1) receives the first image data V1, and the first positional data input portion 140(1) supplies the first positional data L1 (see FIG. 1).

The second display portion 130(2) receives the second image data V2, and the second positional data input portion 140(2) supplies the second positional data L2.

The arithmetic device 110 includes an arithmetic unit 111 and a storage unit 112 that stores a program to be executed by the arithmetic unit 111. The arithmetic unit 111 generates the first image data V1 or the second image data V2 based on the first positional data L1 or the second positional data L2.

The data processor 100 described as an example in this embodiment includes the input/output device 120 that receives image data and supplies positional data, and the arithmetic device 110 that supplies the image data and receives the positional data. The input/output device 120 includes the first region 120(1), the second region 120(2), and the bend portion 120(3) between the first region 120(1) and the second region 120(2). Each of the first region 120(1) and the second region 120(2) includes the display portion and the positional data input portion that overlaps with the display portion. The arithmetic device 110 includes the arithmetic unit 111 and the storage unit 112 that stores a program to be executed by the arithmetic unit 111. Thus, image data can be generated based on positional data supplied from one of the two regions and displayed on the other of the two regions. Consequently, a novel data processor can be provided.

The input/output device 120 may include an input/output unit 145 that supplies and receives data, a sensor unit 150 that senses data outside the data processor 100 and supplies sensed data SENS, and a communication unit 160 that supplies and receives communication data COM.

The arithmetic device 110 may include a transmission path 114 that supplies and receives data, and an input/output interface 115 that supplies and receives data.

Individual components included in the data processor will be described below. Note that these components or units cannot be clearly distinguished and one component/unit also serves as another component/unit or include part of another component/unit in some cases.

For example, a touch panel in which a display portion is overlapped with a touch sensor serves as the positional data input portion 140 as well as the display portion 130.

Note that although this embodiment describes a structure where the positional data input portion 140 is placed on a display surface side of the display portion 130 as an example, one embodiment of the present invention is not limited to this structure. Specifically, the display portion 130 may be placed on a sensing surface side of the positional data input portion 140, or the display portion 130 and the positional data input portion 140 may be integrated into one unit. In other words, either of an on-cell touch panel or an in-cell touch panel may be employed.

<<Entire Structure>>

The data processor 100 includes the input/output device 120 and the arithmetic device 110 (see FIG. 1).

The arithmetic device 110 includes the arithmetic unit 111 and the storage unit 112.

The arithmetic device 110 may further include the transmission path 114 and the input/output interface 115.

<<Input/output Device>>

The input/output device 120 includes the display portion 130 and the positional data input portion 140. The input/output device 120 receives a variety of data and can supply a variety of data.

The input/output device 120 may further include the input/output unit 145, the sensor unit 150, and the communication unit 160.

The input/output device 120 includes the first region 120(1), the second region 120(2), and the bend portion 120 (3) (see FIGS. 2A and 2B).

In a case where the input/output device 120 has a continuous curved surface that includes the first region 120(1) and the second region 120(2), and the first region 120(1) and the second region 120(2) are continuous, for example, the bend portion 120(3) includes a portion with the smallest curvature radius that appears in a section of the curved surface. Although the example in which the input/output device 120 has two second regions 120(2) is shown in FIG. 2B, one embodiment of the present invention is not limited to this example. The input/output device 120 may have only one second region 120(2), or three or more second regions 120(2).

The first region 120(1) includes the first display portion 130(1) and the first positional data input portion 140(1).

The second region 120(2) includes the second display portion 130(2) and the second positional data input portion 140(2). The bend portion 120(3) may also have a display portion and a positional data input portion that overlaps with the display portion. With such a structure, positional data supplied from the bend portion 120(3) may be used instead of the second positional data L2.

For example, two second regions 120(2) may be arranged to face each other (see FIG. 2B). The distance between the two second regions 120(2) is, for example, 17 cm or less, preferably 9 cm or less, and more preferably 7 cm or less. If the distance is short, positional data in a large area of the first positional data input portion 140(1) can be identified or supplied with the use of the thumb of a hand holding the data processor 100.

<<Positional Data Input Portion>>

The positional data input portion 140 senses an approaching object and supplies positional data of the approaching object to the arithmetic device 110. In a case where the positional data input portion 140 has a light-transmitting property, the positional data input portion 140 can be provided closer to a user of the data processor 100 than the display portion 130 is.

For example, the user of the data processor 100 can supply a variety of operating instructions, e.g., a termination instruction (an instruction to terminate a program), to the data processor 100 by making his/her finger, palm, or the like in proximity to the positional data input portion 140.

For example, the proximity sensors 142 may be arranged in a matrix form over a flexible substrate 141 to constitute the positional data input portion 140 (see FIGS. 2C1, 2C2, and 2D).

The positional data input portion 140 includes the first positional data input portion 140(1) and the second positional data input portion 140(2).

The first positional data input portion 140(1) supplies the first positional data L1 and the second positional data input portion 140(2) supplies the second positional data L2.

The first positional data input portion 140(1) and the second positional data input portion 140(2) may be driven as one positional data input portion.

The positional data input portion 140 may be divided into the first positional data input portion 140(1) and the second positional data input portion 140(2) which are driven independently of each other.

Here, X1-X2 direction is set as a row direction, and the direction crossing the row direction is set as a column direction. A plurality of scan lines extending in the row direction, a plurality of signal lines extending in the column direction, and the proximity sensors 142 each including an electrode electrically connected to one scan line and an electrode electrically connected to one signal line are provided in a matrix form in the positional data input portion 140. The plurality of scan lines cut across the first positional data input portion 140(1) and the second positional data input portion 140(2).

The positional data input portion 140 may be divided and driven in the following manner: a proximity sensor having an electrode electrically connected to the signal line provided in the first positional data input portion 140(1) and a proximity sensor having an electrode electrically connected to the signal line provided in the second positional data input portion 140(2) are driven independently of each other.

Specifically, when only the first positional data input portion 140(1) is used, only the proximity sensor provided in the first positional data input portion 140(1) is driven.

When only the second positional data input portion 140(2) is used, only the proximity sensor provided in the second positional data input portion 140(2) is driven.

Note that the scan lines provided across the first positional data input portion 140(1) and the second positional data input portion 140(2) supply signals for driving the proximity sensors to the first positional data input portion 140(1) and the second positional data input portion 140(2) at the same timing. Therefore, in a case where the proximity sensor provided in the first positional data input portion 140(1) and the proximity sensor provided in the second positional data input portion 140(2) are driven independently of each other, a signal for driving the proximity sensor provided in the first positional data input portion 140(1) and a signal for driving the proximity sensor provided in the second positional data input portion 140(2) need to be supplied at different timings.

For example, in a case where the data processor 100 is used with its housing 101 being held by the user's hand, drive of the second positional data input portion 140(2) may be stopped so that only the first positional data input portion 140(1) is driven. Stopping drive of the second positional data input portion 140(2) can reduce malfunctions caused by the second positional data L2 supplied from the second positional data input portion 140(2) that senses the hand holding the data processor 100.

For example, in a case where the sum of power consumed by the first positional data input portion 140(1) and power consumed by the second positional data input portion 140(2) is larger than power consumed only by the first positional data input portion 140(1), drive of the second positional data input portion 140(2) may be stopped so that only the first positional data input portion 140(1) is driven. Specifically, stopping drive of the second positional data input portion 140(2) in a standby state of the data processor 100 can reduce power consumption.

A sensor such as a capacitor or an imaging element can be used as the proximity sensor 142 as long as it can sense an object (e.g., a finger or a palm) approaching or contacting the sensor. Note that a substrate with capacitors arranged in a matrix form can be called a capacitive touch sensor, and a substrate with an imaging element can be called an optical touch sensor (see FIGS. 2C2 and 2D).

As the flexible substrate 141, a resin that is thin enough to have flexibility can be used. Specific examples of the resin include polyester, polyolefin, polyamide (e.g., nylon, aramid), polyimide, polycarbonate, and an acrylic resin.

Alternatively, a normal substrate not having flexibility can be used. For example, a glass substrate, a quartz substrate, or a semiconductor substrate can be used.

Specific structural examples that can be used for the positional data input portion 140 will be described in Embodiments 5, 6, and 7.

<<Display Portion>>

The display portion 130 is not particularly limited as long as it can display image data that is supplied thereto (see FIG. 2C1).

The display portion 130 includes the first display portion 130(1) and the second display portion 130(2).

The first display portion 130(1) displays the first image data V1 that is supplied thereto, and the second display portion 130(2) displays the second image data V2 that is supplied thereto.

The first display portion 130(1) and the second display portion 130(2) may be driven as one display portion.

The first display portion 130(1) and the second display portion 130(2) may be driven as different display portions.

For example, when the data processor 100 is in a standby state, drive of the first display portion 130(1) may be stopped so that only the second display portion 130(2) is driven. Stopping drive of the first display portion 130(1) can reduce power consumption.

Specific structural examples that can be used for the display portion 130 will be described in Embodiments 5, 6, and 7.

<<Sensor Unit>>

The sensor unit 150 senses the states of the data processor 100 and the circumstances and supplies sensed data SENS (see FIG. 1).

The sensor unit 150 senses acceleration, a direction, pressure, a global positioning system (GPS) signal, temperature, or humidity, for example, and may supply data thereof

<<Communication Unit>>

The communication unit 160 supplies data COM supplied from the arithmetic device 110 to a device or a communication network outside the data processor 100. Furthermore, the communication unit 160 acquires the data COM from the device or communication network outside the data processor 100 and supplies the data COM.

The data COM can include a variety of instructions or the like in addition to phonetic data and image data. For example, the data COM can include an operating instruction to generate or delete the first image data V1 and the second image data V2, given to the arithmetic unit 111.

A communication means for connecting to the external device or external communication network, e.g., a hub, a router, or a modem, can be used for the communication unit 160. The connection method is not limited to a method using a wire, and a wireless method (e.g., radio wave or infrared rays) may be used.

<<Input/Output Unit>>

As the input/output unit 145, for example, a camera, a microphone, a read-only external storage unit, an external storage unit, a scanner, a speaker, or a printer can be used (see FIG. 1).

Specifically, as a camera, a digital camera, a digital video camera, or the like can be used.

As an external storage unit, a hard disk, a removable memory, or the like can be used. As a read-only external storage unit, a CD-ROM, a DVD-ROM, or the like can be used.

<<Arithmetic Device>>

The arithmetic device 110 includes the arithmetic unit 111, the storage unit 112, the input/output interface 115, and the transmission path 114 (see FIG. 1).

The arithmetic device 110 receives the first positional data L1 and the second positional data L2 and supplies the first image data V1 and the second image data V2.

For example, the arithmetic device 110 supplies the first image data V1 and the second image data V2 each including an image used for operation of the data processor 100.

The second image data V2 is displayed on the second display portion 130(2). Furthermore, by touching the second positional data input portion 140(2) overlapping with the image used for operation, which is displayed on the second display portion 130(2), with a finger or the like, the user of the data processor 100 can supply an operating instruction related to the image to the arithmetic device 110.

<<Arithmetic Unit>>

The arithmetic unit 111 executes a program stored in the storage unit 112. For example, when positional data related to the position where an image used for operation is supplied, the arithmetic unit 111 executes a program that is related in advance to the image.

<<Storage Unit>>

The storage unit 112 stores the program to be executed by the arithmetic unit 111.

Examples of the program to be executed by the arithmetic unit 111 in the arithmetic device 110 will be described in Embodiments 2 to 4.

<<Input/output Interface and Transmission Path>>

The input/output interface 115 supplies and receives data.

The transmission path 114 can supply data, which is supplied to the arithmetic unit 111, the storage unit 112, and the input/output interface 115. In addition, the arithmetic unit 111, the storage unit 112, and the input/output interface 115 can supply data, which is supplied to the transmission path 114.

The data processor 100 includes the arithmetic device 110, the input/output device 120, and a housing 101 (see FIG. 2B).

<<Housing>>

The housing 101 protects the arithmetic device 110 or the like from stress applied from the outside.

Metal, plastic, glass, ceramics, or the like can be used for the housing 101.

This embodiment can be combined with any of the other embodiments in this specification as appropriate.

Embodiment 2

In this embodiment, a structure of a data processor of one embodiment of the present invention will be described with reference to FIGS. 3A to 3C.

FIGS. 3A and 3B are each a flow chart illustrating a program to be executed by the arithmetic unit 111 of the data processor of one embodiment of the present invention described in Embodiment 1.

Structural Example of Data Processor

The data processor described in this embodiment is provided with the storage unit 112 that stores the program including the following steps.

In a first step, the first image data V1 is generated (S1 in FIG. 3A). Note that a predetermined image or image data generated by another processing can be used.

In a second step, an interrupt processing is allowed (S2 in FIG. 3A). Note that when the interrupt processing is allowed, the arithmetic unit 111 can receive an instruction to execute the interrupt processing. Having received the instruction to execute the interrupt processing, the arithmetic unit 111 stops the main processing and executes the interrupt processing. For example, the arithmetic unit 111 that has received an event related to the instruction executes the interrupt processing and stores the execution result in the storage unit. Then, the arithmetic unit 111 that has returned from the interrupt processing can resume the main processing based on the execution result of the interrupt processing.

In a third step, the first image data V1 is displayed (S3 in FIG. 3A).

In a fourth step, a fifth step is selected when a termination instruction is supplied in the interrupt processing, and the third step is selected when no termination instruction is supplied in the interrupt processing (S4 in FIG. 3A).

In the fifth step, the program terminates (S5 in FIG. 3A).

The interrupt processing includes the following steps.

In a sixth step, a seventh step is selected when an instruction is supplied from the second positional data input portion 140(2), and an eighth step is selected when no instruction is supplied from the second positional data input portion 140(2) (T6 in FIG. 3B).

For example, the second positional data input portion 140(2) senses the position of a finger of the user of the data processor, which touches the second region 120(2) and supplies the second positional data L2. The arithmetic unit 111 can analyze the locus of the second positional data L2 and identify a variety of gestures (e.g., tap, drag, swipe, pinch-in, and pinch-out) of the user of the data processor using his/her finger as a pointer (for example, see FIG. 3C).

Specifically, the arithmetic unit 111 can relate, an instruction to sequentially select one image from a plurality of images to be displayed, to the tap or the like.

Furthermore, the arithmetic unit 111 can relate, an instruction to scroll and move a long band-like image, to the drag, swipe, or the like.

Furthermore, the arithmetic unit 111 can relate, an instruction to change the size of an image to be displayed, to the pinch-in, pinch-out, or the like.

In the seventh step, the first image data V1 is generated based on the instruction (T7 in FIG. 3B).

In the eighth step, the operation returns from the interrupt processing (T8 in FIG. 3B).

The data processor 100 described in this embodiment includes the step of generating the first image data V1 based on the second positional data L2. Thus, image data to be displayed on the first region can be determined with the use of the second positional data input portion. Consequently, a novel data processor can be provided.

Modification Example of Data Processor

Another structure of a data processor of one embodiment of the present invention will be described with reference to FIGS. 4A and 4B.

FIG. 4A is a flow chart illustrating a modification example of the interrupt processing of the program described with reference to FIG. 3B.

The data processor described in this embodiment is provided with the storage unit 112 that stores a program including the following steps.

The data processor 100 described as a modification example in this embodiment is different from the data processor 100 described with reference to FIG. 3B in that, a step of selecting the eighth step when a termination instruction is supplied from the second positional data input portion 140(2) is included after the sixth step. Different structures will be described in detail below, and the above description is referred to for the other similar structures.

Note that in this specification, “termination instruction” refers to an instruction to terminate a program in processing; an instruction to stop the supply of a power supply potential to a power source of the data processor; an instruction to start a program, which includes a series of processing to be performed before stopping the supply of a power supply potential and a termination instruction thereof; and the like.

The data processor described in this embodiment is provided with the storage unit 112 that stores a program of an interrupt processing including the following steps.

In the sixth step, a step 6.1 is selected when an instruction is supplied from the second positional data input portion 140(2), and the eighth step is selected when no instruction is supplied from the second positional data input portion 140(2) (T6 in FIG. 4A).

In the step 6.1, the eighth step is selected when positional data related to a termination instruction is supplied from the second positional data input portion 140(2), and a seventh step is selected when no positional data related to a termination instruction is supplied from the second positional data input portion 140(2) (T6.1 in FIG. 4A).

For example, the second positional data input portion 140(2) senses the position of a finger of the user of the data processor, which touches the second region 120(2) and supplies the second positional data L2. The arithmetic unit 111 can analyze the locus of the second positional data L2 and identify a variety of gestures (e.g., tap, drag, swipe, pinch-in, and pinch-out) of the user of the data processor using his/her finger as a pointer.

Specifically, the arithmetic unit 111 can relate a termination instruction to a gesture of touching predetermined two points in the second positional data input portion 140(2) for a longer period than a predetermined period.

In the seventh step, the first image data V1 is generated based on the instruction (T7 in FIG. 4A).

In the eighth step, the operation returns from the interrupt processing (T8 in FIG. 4A).

The data processor described in this embodiment includes a step of returning from the interrupt processing and supplying the termination instruction when the positional data L2 supplied from the second positional data input portion 140(2) is related to the termination instruction. Thus, the termination instruction can be supplied with the use of the second region. Consequently, a novel data processor can be provided (see, for example, FIG. 4B).

This embodiment can be combined with any of the other embodiments in this specification as appropriate.

Embodiment 3

In this embodiment, a structure of a data processor of one embodiment of the present invention will be described with reference to FIGS. 5A to 5C and FIG. 6.

FIG. 5A is a flow chart illustrating a program to be executed by the arithmetic unit 111 of the data processor of one embodiment of the present invention described in Embodiment 1.

FIG. 6 is a flow chart illustrating an interrupt processing of a program described with reference to FIG. 5A.

Structural Example of Data Processor

The data processor described in this embodiment is provided with the storage unit 112 that stores a program including the following steps.

In a first step, initial data including status data is acquired (U1 in FIG. 5A).

The status data is a sign that determines the operation of the data processor. The data processor performs a predetermined operation based on the status data.

For example, when the stats data shows a first status, the arithmetic unit 111 generates the first image data V1 and displays the first image data V1 on the first display portion 130(1).

When the status data shows a second status, the arithmetic unit 111 generates the second image data V2 and displays the second image data V2 on the second display portion 130(2).

In a second step, the interrupt processing is allowed (U2 in FIG. 5A).

In a third step, predetermined data is acquired (U3 in FIG. 5A).

For example, data to be displayed on the display portion is acquired.

In a fourth step, a fifth step is selected when the status data shows the first status and a sixth step is selected when the status data shows the second status (U4 in FIG. 5A).

For example, in a case where the first display portion 130(1) and the second display portion 130(2) are different in size, arrangement of data that is suitable for the first display portion 130(1) is not necessarily suitable for the second display portion 130(2). In that case, the display portion on which the data is displayed may be changed based on the status data. In addition, image data in which the data is arranged to be displayed suitably on the display portion may be generated.

Specifically, the first display portion 130(1) having a larger area than the second display portion 130(2) can display several lines of text at a time (for example, see FIG. 5B).

In contrast, a method in which one line is sequentially selected from several lines to be displayed or a method in which text is displayed in a flowing manner is preferred for the second display portion 130(2) having a narrow and long shape. In this way, the acquired predetermined data can be displayed using an appropriate size of characters (for example, see FIG. 5C).

In the fifth step, the first image data V1 is generated based on the acquired data, and the first image data V1 is displayed on the first display portion 130(1) (U5 in FIG. 5A).

In the sixth step, the second image data V2 is generated based on the acquired data, and the second image data V2 is displayed on the second display portion 130(2) (U6 in FIG. 5A).

In a seventh step, an eighth step is selected when a termination instruction is supplied in the interrupt processing and the third step is selected when no termination instruction is supplied in the interrupt processing (U7 in FIG. 5A).

In the eighth step, the program terminates (U8 in FIG. 5A).

The interrupt processing includes the following steps.

In a ninth step, a tenth step is selected when an instruction to set status data is supplied and an eleventh step is selected when no instruction to set status data is supplied (V9 in FIG. 6).

The user of the data processor can select and set as appropriate the status data that determines the operation of the data processor. Thus, the user can conveniently use the data processor.

Specifically, an instruction to set the status data to first status data is supplied in a case where the user wants a method in which the acquired data is displayed only on the first display portion.

Alternatively, an instruction to set the status data to second status data is supplied in a case where the user wants a method in which the acquired data is displayed only on the second display portion.

In the tenth step, the status data is updated based on the supplied instruction (V10 in FIG. 6).

In the eleventh step, the operation returns from the interrupt processing (V11 in FIG. 6).

The data processor described in this embodiment includes the step of acquiring predetermined data, the step of setting status data, and the step of generating image data including the acquired predetermined data based on the set status data and displaying the image data on the display portion. Thus, the image including the predetermined data can be displayed on a region that is set based on the status data. Consequently, a novel data processor can be provided.

This embodiment can be combined with any of the other embodiments in this specification as appropriate.

Embodiment 4

In this embodiment, a structure of a data processor of one embodiment of the present invention will be described with reference to FIGS. 7A and 7B and FIG. 8.

FIG. 7A is a flow chart illustrating a program to be executed by the arithmetic unit 111 of the data processor of one embodiment of the present invention described in Embodiment 1.

FIG. 8 is a flow chart illustrating an interrupt processing of the program described with reference to FIGS. 7A and 7B.

Structural Example of Data Processor

The data processor described in this embodiment is provided with the storage unit 112 that stores the program including the following steps.

In a first step, an interrupt processing is allowed (W1 in FIG. 7A).

In a second step, a third step is selected when there is an incoming email/call, and a fifth step is selected when there is no incoming email/call (W2 in FIG. 7A).

For example, a data processor provided with the communication unit 160 that communicates data with a communication network can receive an email from the communication network. A data processor provided with the input/output unit 145 capable of outputting and inputting phonetic data, in addition to the communication unit, can receive a call.

In the third step, data on a sender/caller is acquired (W3 in FIG. 7A).

With the use of an email address/phone number of the sender/caller, an address book stored in the storage unit 112 is searched, so that data on the sender/caller can be acquired.

In a fourth step, the second image data including data on the sender/caller is generated, and the second image data is displayed (W4 in FIG. 7A).

In the fifth step, a sixth step is selected when a termination instruction is supplied in the interrupt processing and the second step is selected when no termination instruction is supplied in the interrupt processing (W5 in FIG. 7A).

In the sixth step, the program terminates (W6 in FIG. 7A).

The interrupt processing includes the following steps.

In a seventh step, an eighth step is selected in a case where the incoming email/call is to be opened/answered, and a ninth step is selected in a case where the incoming email/call is not to be opened/answered (X7 in FIG. 8).

In the eighth step, the incoming email/call is opened/answered (X8 in FIG. 8).

For example, an instruction to open/answer the incoming email/call can be supplied with the use of a switch or the like provided in the input/output unit 145 or a predetermined gesture from the positional data input portion 140.

Specifically, an application that enables reading and creating emails is started and the received email is read, or an application of telephone is started and phone talk is started.

In the ninth step, display of the second image data is stopped (X9 in FIG. 8).

For example, an instruction to reject the incoming email/call can be supplied with the use of a switch or the like provided in the input/output unit 145 or a predetermined gesture from the positional data input portion 140.

In a tenth step, the operation returns from the interrupt processing (X10 in FIG. 8).

The data processor of one embodiment of the present invention includes the step of displaying the phone number of the incoming call in its standby state and data related to the phone number on the second display portion (for example, see FIG. 7B). Thus, the phone number of the incoming call and data related thereto can be displayed. Consequently, a novel data processor can be provided.

This embodiment can be combined with any of the other embodiments in this specification as appropriate.

A touch panel 300 described as an example in this embodiment includes a display portion 301 (see FIG. 9A).

The display portion 301 includes a plurality of pixels 302 and a plurality of imaging pixels 308. The imaging pixels 308 can sense a touch of a finger or the like on the display portion 301. Thus, a touch sensor can be formed using the imaging pixels 308.

Each of the pixels 302 includes a plurality of sub-pixels (e.g., a sub-pixel 302R). In addition, in the sub-pixels, light-emitting elements and pixel circuits that can supply electric power for driving the light-emitting elements are provided.

The pixel circuits are electrically connected to wirings through which selection signals are supplied and wirings through which image signals are supplied.

Furthermore, the touch panel 300 is provided with a scan line driver circuit 303 g(1) that can supply selection signals to the pixels 302 and an image signal line driver circuit 303 s(1) that can supply image signals to the pixels 302.

The imaging pixels 308 include photoelectric conversion elements and imaging pixel circuits that drive the photoelectric conversion elements.

The imaging pixel circuits are electrically connected to wirings through which control signals are supplied and wirings through which power supply potentials are supplied.

Examples of the control signals include a signal for selecting an imaging pixel circuit from which a recorded imaging signal is read, a signal for initializing an imaging pixel circuit, and a signal for determining the time it takes for an imaging pixel circuit to sense light.

The touch panel 300 is provided with an imaging pixel driver circuit 303 g(2) that can supply control signals to the imaging pixels 308 and an imaging signal line driver circuit 303 s(2) that reads out imaging signals.

<Cross-Sectional View>

The touch panel 300 includes a substrate 310 and a counter substrate 370 that faces the substrate 310 (see FIG. 9B).

The substrate 310 is a stacked body in which a flexible substrate 310 b, a barrier film 310 a that prevents diffusion of unintentional impurities to the light-emitting elements, and a resin layer 310 c that attaches the barrier film 310 a to the substrate 310 b are stacked.

The counter substrate 370 is a stacked body in which a flexible substrate 370 b, a barrier film 370 a that prevents diffusion of unintentional impurities to the light-emitting elements, and a resin layer 370 c that attaches the barrier film 370 a to the substrate 370 b are stacked (see FIG. 9B).

A sealant 360 attaches the counter substrate 370 to the substrate 310. The sealant 360 also serving as an optical adhesive layer has a refractive index higher than that of air. The pixel circuits and the light-emitting elements (e.g., a first light-emitting element 350R) are provided between the substrate 310 and the counter substrate 370.

<<Structure of Pixels>>

Each of the pixels 302 includes the sub-pixel 302R, a sub-pixel 302G, and a sub-pixel 302B (see FIG. 9C). The sub-pixel 302R includes a light-emitting module 380R, the sub-pixel 302G includes a light-emitting module 380G, and the sub-pixel 302B includes a light-emitting module 380B.

For example, the sub-pixel 302R includes the first light-emitting element 350R and the pixel circuit that can supply electric power to the first light-emitting element 350R and includes a transistor 302 t (see FIG. 9B). Furthermore, the light-emitting module 380R includes the first light-emitting element 350R and an optical element (e.g., a first coloring layer 367R).

The first light-emitting element 350R includes a first lower electrode 351R, an upper electrode 352, and a layer 353 containing a light-emitting organic compound between the first lower electrode 351R and the upper electrode 352 (see FIG. 9C).

The layer 353 containing a light-emitting organic compound includes a light-emitting unit 353 a, a light-emitting unit 353 b, and an intermediate layer 354 between the light-emitting units 353 a and 353 b.

The light-emitting module 380R includes the first coloring layer 367R on the counter substrate 370. The coloring layer transmits light of a particular wavelength and is, for example, a layer that selectively transmits light of red, green, or blue color. A region that transmits light emitted from the light-emitting element as it is may be provided as well.

The light-emitting module 380R, for example, includes the sealant 360 that is in contact with the first light-emitting element 350R and the first coloring layer 367R.

The first coloring layer 367R is positioned in a region overlapping with the first light-emitting element 350R. Accordingly, part of light emitted from the first light-emitting element 350R passes through the sealant 360 that also serves as an optical adhesive layer and through the first coloring layer 367R and is emitted to the outside of the light-emitting module 380R as indicated by arrows in FIGS. 9B and 9C.

<<Structure of Display Panel>>

The touch panel 300 includes a light-blocking layer 367BM on the counter substrate 370. The light-blocking layer 367BM is provided so as to surround the coloring layer (e.g., the first coloring layer 367R).

The touch panel 300 includes an anti-reflective layer 367 p positioned in a region overlapping with the display portion 301. As the anti-reflective layer 367 p, a circular polarizing plate can be used, for example.

The touch panel 300 includes an insulating film 321. The insulating film 321 covers the transistor 302 t. Note that the insulating film 321 can be used as a layer for planarizing unevenness caused by the pixel circuits. An insulating film on which a layer that can prevent diffusion of impurities to the transistor 302 t and the like is stacked can be used as the insulating film 321.

The touch panel 300 includes the light-emitting elements (e.g., the first light-emitting element 350R) over the insulating film 321.

The touch panel 300 includes, over the insulating film 321, a partition wall 328 that overlaps with an end portion of the first lower electrode 351R (see FIG. 9C). In addition, a spacer 329 that controls the distance between the substrate 310 and the counter substrate 370 is provided on the partition wall 328.

<<Structure of Image Signal Line Driver Circuit>>

The image signal line driver circuit 303 s(1) includes a transistor 303 t and a capacitor 303 c. Note that the driver circuit can be formed in the same process and over the same substrate as those of the pixel circuits.

<<Structure of Imaging Pixel>>

The imaging pixels 308 each include a photoelectric conversion element 308 p and an imaging pixel circuit for sensing light received by the photoelectric conversion element 308 p. The imaging pixel circuit includes a transistor 308 t.

For example, a PIN photodiode can be used as the photoelectric conversion element 308 p.

<<Other Components>>

The touch panel 300 includes a wiring 311 through which a signal can be supplied. The wiring 311 is provided with a terminal 319. Note that an FPC 309(1) through which a signal such as an image signal or a synchronization signal can be supplied is electrically connected to the terminal 319.

Note that a printed wiring board (PWB) may be attached to the FPC 309(1).

Transistors formed in the same process can be used as the transistor 302 t, the transistor 303 t, the transistor 308 t, and the like.

Transistors of a bottom-gate type, a top-gate type, or the like can be used.

Any of various kinds of semiconductors can be used in the transistors. For example, an oxide semiconductor, single crystal silicon, polysilicon, amorphous silicon, or the like can be used.

This embodiment can be combined with any of the other embodiments in this specification as appropriate.

Embodiment 6

In this embodiment, a structure of a foldable/bendable touch panel that can be used in a data processor of one embodiment of the present invention will be described with reference to FIGS. 10A and 10B and FIGS. 11A to 11C.

FIG. 10A is a perspective view of a touch panel 500 described as an example in this embodiment. Note that FIGS. 10A and 10B illustrate only main components for simplicity. FIG. 10B is a developed perspective view of the touch panel 500.

FIG. 11A is a cross-sectional view of the touch panel 500 taken along line X1-X2 in FIG. 10A.

The touch panel 500 includes a display portion 501 and a touch sensor 595 (see FIG. 10B). Furthermore, the touch panel 500 includes a substrate 510, a substrate 570, and a substrate 590. Note that the substrate 510, the substrate 570, and the substrate 590 each have flexibility.

The display portion 501 includes the substrate 510, a plurality of pixels over the substrate 510, and a plurality of wirings 511 through which signals are supplied to the pixels. The plurality of wirings 511 is led to a peripheral portion of the substrate 510, and part of the plurality of wirings 511 forms a terminal 519. The terminal 519 is electrically connected to an FPC 509(1).

<Touch Sensor>

The substrate 590 includes the touch sensor 595 and a plurality of wirings 598 electrically connected to the touch sensor 595. The plurality of wirings 598 is led to a peripheral portion of the substrate 590, and part of the plurality of wirings 598 forms a terminal. The terminal is electrically connected to an FPC 509(2). Note that in FIG. 10B, electrodes, wirings, and the like of the touch sensor 595 provided on the back side of the substrate 590 (on the back side of the diagram) are indicated by solid lines for clarity.

As the touch sensor 595, a capacitive touch sensor can be used, for example. Examples of the capacitive touch sensor are a surface capacitive touch sensor and a projected capacitive touch sensor.

Examples of the projected capacitive touch sensor are a self-capacitive touch sensor and a mutual capacitive touch sensor, which differ mainly in the driving method. The use of a mutual capacitive touch sensor is preferable because multiple points can be sensed simultaneously.

An example of using a projected capacitive touch sensor will be described below with reference to FIG. 10B.

Note that a variety of sensors that can sense an approaching or contacting target, such as a finger, can be used.

The projected capacitive touch sensor 595 includes electrodes 591 and electrodes 592. The electrodes 591 are electrically connected to any of the plurality of wirings 598, and the electrodes 592 are electrically connected to any of the other wirings 598.

The electrodes 592 each have a shape of a plurality of quadrangles arranged in one direction with one corner of a quadrangle connected to one corner of another quadrangle as illustrated in FIGS. 10A and 10B.

The electrodes 591 each have a quadrangular shape and are arranged in a direction intersecting with the direction in which the electrodes 592 extend.

A wiring 594 electrically connects two electrodes 591 between which the electrode 592 is positioned. The intersecting area of the electrode 592 and the wiring 594 is preferably as small as possible. Such a structure allows a reduction in the area of a region where the electrodes are not provided, reducing unevenness in transmittance. As a result, unevenness in luminance of light passing through the touch sensor 595 can be reduced.

Note that the shapes of the electrodes 591 and the electrodes 592 are not limited to the above-mentioned shapes and can be any of a variety of shapes. For example, the plurality of electrodes 591 may be provided so that space between the electrodes 591 are reduced as much as possible, and a plurality of electrodes 592 may be provided with an insulating layer positioned between the electrodes 591 and the electrodes 592 and may be spaced apart from each other to form a region not overlapping with the electrodes 591. In that case, between two adjacent electrodes 592, it is preferable to provide a dummy electrode which is electrically insulated from these electrodes, whereby the area of a region having a different transmittance can be reduced.

The structure of the touch sensor 595 is described with reference to FIGS. 11A, 11B, and 11C.

The touch sensor 595 includes the substrate 590, the electrodes 591 and the electrodes 592 provided in a staggered arrangement on the substrate 590, an insulating layer 593 covering the electrodes 591 and the electrodes 592, and the wiring 594 that electrically connects the adjacent electrodes 591 to each other.

A resin layer 597 attaches the substrate 590 to the substrate 570 so that the touch sensor 595 overlaps with the display portion 501.

The electrodes 591 and the electrodes 592 are formed using a light-transmitting conductive material. As a light-transmitting conductive material, a conductive oxide such as indium oxide, indium tin oxide, indium zinc oxide, zinc oxide, or zinc oxide to which gallium is added can be used. A film containing graphene may be used as well. The film containing graphene can be formed, for example, by reducing a film containing graphene oxide. As a reducing method, a method with application of heat or the like can be employed.

The electrodes 591 and the electrodes 592 may be formed by depositing a light-transmitting conductive material on the substrate 590 by a sputtering method and then removing an unnecessary portion by any of various patterning techniques such as photolithography.

Examples of a material for the insulating layer 593 are a resin such as acrylic or epoxy resin, a resin having a siloxane bond, and an inorganic insulating material such as silicon oxide, silicon oxynitride, or aluminum oxide.

Furthermore, openings reaching the electrodes 591 are formed in the insulating layer 593, and the wiring 594 electrically connects the adjacent electrodes 591. A light-transmitting conductive material can be favorably used as the wiring 594 because the aperture ratio of the touch panel can be increased. Moreover, a material with higher conductivity than the conductivities of the electrodes 591 and 592 can be favorably used as the wiring 594 because electric resistance can be reduced.

One electrode 592 extends in one direction, and a plurality of electrodes 592 is provided in the form of stripes.

The wiring 594 intersects with the electrode 592.

Adjacent electrodes 591 are provided with one electrode 592 provided therebetween. The wiring 594 electrically connects the adjacent electrodes 591.

Note that the plurality of electrodes 591 is not necessarily arranged in the direction orthogonal to one electrode 592 and may be arranged to intersect with one electrode 592 at an angle of less than 90 degrees.

One wiring 598 is electrically connected to any of the electrodes 591 and 592. Part of the wiring 598 serves as a terminal. For the wiring 598, a metal material such as aluminum, gold, platinum, silver, nickel, titanium, tungsten, chromium, molybdenum, iron, cobalt, copper, or palladium or an alloy material containing any of these metal materials can be used.

Note that an insulating layer that covers the insulating layer 593 and the wiring 594 may be provided to protect the touch sensor 595.

Furthermore, a connection layer 599 electrically connects the wiring 598 to the FPC 509(2).

As the connection layer 599, any of various anisotropic conductive films (ACF), anisotropic conductive pastes (ACP), or the like can be used.

The resin layer 597 has a light-transmitting property. For example, a thermosetting resin or an ultraviolet curable resin can be used; specifically, a resin such as an acrylic resin, an urethane resin, an epoxy resin, or a resin having a siloxane bond can be used.

<Display Portion>

The display portion 501 includes a plurality of pixels arranged in a matrix. Each of the pixels includes a display element and a pixel circuit for driving the display element.

In this embodiment, an example of using an organic electroluminescent element that emits white light as a display element will be described; however, the display element is not limited to such element.

For example, organic electroluminescent elements that emit light of different colors may be included in sub-pixels so that the light of different colors can be emitted from the respective sub-pixels.

Other than organic electroluminescent elements, any of various display elements such as display elements (electronic ink) that perform display by an electrophoretic method, an electronic liquid powder method, an electrowetting method, or the like; MEMS shutter display elements; optical interference type MEMS display elements; and liquid crystal elements can be used. Furthermore, this embodiment can be used in a transmissive liquid crystal display, a transflective liquid crystal display, a reflective liquid crystal display, a direct-view liquid crystal display, or the like. A structure suitable for employed display elements can be selected from among a variety of structures of pixel circuits.

In the display portion, an active matrix method in which an active element is included in a pixel or a passive matrix method in which an active element is not included in a pixel can be used.

In an active matrix method, as an active element (a non-linear element), not only a transistor but also various active elements (non-linear elements) can be used. For example, a metal insulator metal (MIM), a thin film diode (TFD), or the like can also be used. Since such an element has few numbers of manufacturing steps, manufacturing cost can be reduced or yield can be improved. Alternatively, since the size of the element is small, the aperture ratio can be improved, so that power consumption can be reduced or higher luminance can be achieved.

As a method other than the active matrix method, the passive matrix method in which an active element (a non-linear element) is not used can also be used. Since an active element (a non-linear element) is not used, the number of manufacturing steps is small, so that manufacturing cost can be reduced or yield can be improved. Alternatively, since an active element (a non-linear element) is not used, the aperture ratio can be improved, so that power consumption can be reduced or higher luminance can be achieved, for example.

Flexible materials can be favorably used in the substrate 510 and the substrate 570.

Materials with which unintended passage of impurities is inhibited can be favorably used in the substrate 510 and the substrate 570. For example, materials with a vapor permeability of lower than or equal to 10⁻⁵ g/m²·day, preferably lower than or equal to 10⁻⁶ g/m²·day can be favorably used.

The substrate 510 can be favorably formed using a material whose coefficient of linear expansion is substantially equal to that of the substrate 570. For example, the coefficient of linear expansion of the materials are preferably lower than or equal to 1×10⁻³/K, further preferably lower than or equal to 5×10⁻⁵/K, and still further preferably lower than or equal to 1×10⁻⁵/K.

The substrate 510 is a stacked body in which a flexible substrate 510 b, a barrier film 510 a that prevents diffusion of unintentional impurities to light-emitting elements, and a resin layer 510 c that attaches the barrier film 510 a to the substrate 510 b are stacked.

For example, materials that include polyester, polyolefin, polyamide (e.g., nylon, aramid), polyimide, polycarbonate, or a resin having an acrylic bond, an urethane bond, an epoxy bond, or a siloxane bond can be used for the resin layer 510 c.

The substrate 570 is a stacked body in which a flexible substrate 570 b, a barrier film 570 a that prevents diffusion of unintentional impurities to the light-emitting elements, and a resin layer 570 c that attaches the barrier film 570 a to the substrate 570 b are stacked.

A sealant 560 attaches the substrate 570 to the substrate 510. The sealant 560 has a refractive index higher than that of air. In a case where light is extracted to the sealant 560 side, the sealant 560 serves as an optical adhesive layer. The pixel circuits and the light-emitting elements (e.g., a first light-emitting element 550R) are provided between the substrate 510 and the substrate 570.

<<Structure of Pixel>>

A pixel includes a sub-pixel 502R, and the sub-pixel 502R includes a light-emitting module 580R.

The sub-pixel 502R includes the first light-emitting element 550R and the pixel circuit, which can supply electric power to the first light-emitting element 550R and includes a transistor 502 t. Furthermore, the light-emitting module 580R includes the first light-emitting element 550R and an optical element (e.g., a first coloring layer 567R).

The first light-emitting element 550R includes a lower electrode, an upper electrode, and a layer containing a light-emitting organic compound between the lower electrode and the upper electrode.

The light-emitting module 580R includes the first coloring layer 567R on the light extraction side. The coloring layer transmits light of a particular wavelength and is, for example, a layer that selectively transmits light of red, green, or blue color. Note that in another sub-pixel, a region that transmits light emitted from the light-emitting element as it is may be provided as well.

In a case where the sealant 560 is provided on the light extraction side, the sealant 560 is in contact with the first light-emitting element 550R and the first coloring layer 567R.

The first coloring layer 567R is positioned in a region overlapping with the first light-emitting element 550R. Accordingly, part of light emitted from the first light-emitting element 550R passes through the first coloring layer 567R and is emitted to the outside of the light-emitting module 580R as indicated by an arrow in FIG. 11A.

<<Structure of Display Portion>>

The display portion 501 includes a light-blocking layer 567BM on the light extraction side. The light-blocking layer 567BM is provided so as to surround the coloring layer (e.g., the first coloring layer 567R).

The display portion 501 includes an anti-reflective layer 567 p positioned in a region overlapping with pixels. As the anti-reflective layer 567 p, a circular polarizing plate can be used, for example.

The display portion 501 includes an insulating film 521. The insulating film 521 covers the transistor 502 t. Note that the insulating film 521 can be used as a layer for planarizing unevenness caused by the pixel circuit. A stacked film including a layer that can prevent diffusion of impurities can be used as the insulating film 521. This can prevent the reliability of the transistor 502 t or the like from being lowered by diffusion of unintentional impurities.

The display portion 501 includes the light-emitting elements (e.g., the first light-emitting element 550R) over the insulating film 521.

The display portion 501 includes, over the insulating film 521, a partition wall 528 that overlaps with an end portion of the first lower electrode. In addition, a spacer that controls the distance between the substrate 510 and the substrate 570 is provided on the partition wall 528.

<<Structure of Scan Line Driver Circuit>>

The light-emitting module 580R includes the first coloring layer 567R on the light extraction side. The coloring layer transmits light of a particular wavelength and is, for example, a layer that selectively transmits light of red, green, or blue color. Note that in another sub-pixel, a region that transmits light emitted from the light-emitting element as it is may be provided as well.

The first coloring layer 567R is positioned in a region overlapping with the first light-emitting element 550R. The first light-emitting element 550R shown in FIG. 12A emits light to the side where the transistor 502 t is provided. Accordingly, part of light emitted from the first light-emitting element 550R passes through the first coloring layer 567R and is emitted to the outside of the light-emitting module 580R as indicated by an arrow in FIG. 12A.

<<Structure of Display Portion>>

A stacked film including a layer that can prevent diffusion of impurities can be used as the insulating film 521. This can prevent reliability of the transistor 502 t or the like from being lowered by diffusion of unintentional impurities from the first coloring layer 567R.
